Attach the Grille
1. If lighted grille is being used, plug wire into fan
socket.
If lighted grille and ceiling radiation damper are
being used, plug wire from lighted grille into ceiling
radiation damper socket. Do not plug wire directly
into the fan socket. Make sure the wire does not
interfere with the ceiling radiation damper operation.
2. Attach grille with two screws provided. Make sure
not to over tighten; over tightening will damage
grille.
3. Slide attachment screw covers over the attachment
screws, shown in Figure 8 and 9.
4. If lighted grille is being used, install light bulb(s) into
light socket(s). For incandescent lights, use maximum
100 watt bulb (by others). For fluorescent lights, use
27W GU24 bulbs. Greenheck has replacement 27W
GU24 bulbs call 1-800-355-5354 to order.
5. If lighted grille is being used, snap lens into place, by
pushing on the outside edges of lens, shown in Fig. 9.
To remove lens, use small screw driver and pry on
one side of lens.
6. Turn on power and check fan and light operation.
